| Abstract: | A method for the dynamic analysis of spatial mechanisms with large displacement and variable kinematic structure is presented in this paper. The motion and deformation of each body is described using relative coordinates and finite element modal coordinates. Relative motion compatibility conditions are developed to gurantee a smooth transition from one configuration to another. Dynamic equations are established of the system to consist of a set of rigid and flexible bodies. The method is exemplified using a Rocket Launcher system with variable kinematic structure and have a good accuracy and reliability. |
